Installing Squid NT on Windows 7

Squid is a caching proxy server that can help reduce internet bandwidth usage and improving response time of loading a website by caching and re-using frequently opened web page. Squid reduce the bandwidth usage and accelerate the website loading by caching static website objects such as images, flash objects and text files, with some modification Squid can cache larger files such as PDF, MP3, executables, flash videos, etc.

Installing TinyProxy as Squid Proxy Server Alternative

Tinyproxy is a light-weight HTTP proxy daemon for POSIX operating systems. It is distributed using the GNU GPL license version 2 or above, so we can download it and install it on our Linux server freely.

Tinyproxy is a light-weight alternative for the well known Squid proxy server. It’s really memory efficient so it will run perfectly fine in small VPS (Virtual Private Server) and being used for several users. Several features of Tinyproxy are:

  • Small footprint: Tinyproxy requires very little in the way of system resources. The memory footprint tends to be around 2 MB with glibc, and the CPU load increases linearly with the number of simultaneous connections (depending on the speed of the connection). Thus, Tinyproxy can be run on an older machine, or on a network appliance such as a Linux-based broadband router, without any noticeable impact on performance.
  • Minimal requirements: Tinyproxy doesn’t require anything more than a POSIX environment to build and operate. It can use additional libraries to add functionality though.
  • Easily modified: If you’re looking to build a custom web proxy, Tinyproxy is very easy to modify to your custom needs. The source is straightforward, adhering to the KISS principle. As such, it can be used as a foundation for anything you may need a web proxy to do.
  • Anonymous mode: Allows you to specify which HTTP headers should be allowed through, and which should be blocked. This allows you to restrict both what data comes to your web browser from the HTTP server (eg., cookies), and to restrict what data is allowed through from your web browser to the HTTP server (eg., version information).
  • Remote monitoring: Using the remote monitoring feature, you can access proxy statistics from afar, letting you know exactly how busy the proxy is.
  • Load average monitoring: Tinyproxy can be configured to watch the load average on most platforms, and start refusing requests when the load reaches a certain point. You may recognize this feature from Sendmail.
  • Access control: You can configure Tinyproxy to only allow requests from a certain subnet, or from a certain interface, thus allowing you to ensure that random, unauthorized people will not be using your proxy.
  • Secure: With a bit of configuration (specifically, making the log file owned by nobody and running it on a port > 1024), Tinyproxy can be made to run without any special privileges, thus minimizing the chance of system compromise. Furthermore, it was designed with an eye towards preventing buffer overflows. The simplicity of the code ensures it remains easy to spot such bugs.

From Squid NT website it’s stated: “Transparent Proxy: missing Windows non commercial interception driver”. Continue reading Squid Transparent Proxy Server on Windows Server 2003

Installing Squid Cache for Windows

Linux users mostly already know Squid proxy server as the best and most used proxy server. As on my previous post “Bandwidth Shaping Using Squid Cache and WIPFW” I need a free proxy server for my windows server. I found SquidNT which is ported from its Linux version by Guido Serassio.

You can download SquidNT from Acme Consulting’s website or here. If you want to do bandwidth shaping then you must download SquidNT with Delay Pool version. On this installation guide, I use the Delay Pool version as I want to do bandwidth shaping.

Bandwidth Shaping Using Squid Cache and WIPFW

It’s been a few times I’m trying to find free proxy server and firewall for windows server on my office, but I haven’t found any luck until 3 days ago.

I have been stressed by colleagues that running bittorrent download or downloading big files using download manager in the office hours. Both torrent and download manager sucks all the bandwidth and causing other user nearly can’t even browse the web.
